CL-Out bioremediation of groundwater in clay soils reduced concentrations of PCE and TCE at a former dry cleaners in Illinois. In just over 2 weeks after injection, CL-Out microbes cut the contaminant concentrations in half.
- PCE from 62.2 to 25.6 mg/L
- TCE from 11.2 to 6.0 mg/L
- Cis 1,2-DCE from 3.8 to 1.2 mg/L
- Vinyl chloride less than 0.001 mg/L before and after treatment
The remediation continues as the microbes grow and cometabolize the residual contamination. Even in tight clay soils the aerobic cometabolism remediates dry cleaning solvents without producing vinyl chloride or other dangerous by products.
